ondary lateral ones joining it above the middle, coarsely retic- 
ulate; bud bract 3 to 10 mm. long, glabrous; stipule acuminate,

or in the axils of the leaf scars, from 5 to 10 mm. in diameter,

the 5 inner ones lanceolate and opposite; ovary glabrous,

Type specimen 10337, A. D. E. Elmer, Dumaguete, Cuer- 
nos Mountains, Province of Negros Oriental, Negros, June, 
1908. 
A very lax and slenderly branched shrub hanging on 
cliffs near the Bonyao river at 1250 feet. It has very much 
the general foliage appearance and lax branching habit of cer- 
tain Philippine Pipers. 
In the field I took it for a very large lax form of E. 
rigidum Wedd. but it is most unlike 1674 Cuming. It is, 
however, very similar to E. rostratum Miq., but more dis- 
similar to E. rostratum manillensis Wedd. 
Elatostema hastatum Elm. n. sp. 
Sueculent herb; stems prostrate, trailing, the sparse bran- 
ches suberect, easily breaking, terete, green, covered with 
dirty setose hairs, 2 mm. thick. Leaves submembranous, nearly 
flat, alternatingly scattered in distichous rows, 3 to 5 mm. 
apart, subglaucous green on the upper side, pale or light green 
beneath, squarrosely oblong, 15 mm. long by 6 mm. wide, 
dark brown on the upper side when dry, much lighter beneath, 
divaricate, pseudostrigose on both sides, the nerves only sparsely 
strigose or more densely so on the lower side toward the 
base, beneath very finely glandular, subsessile, the basal 
one half with entire margins, coarsely dentate above the middle, 
inequilateral, the apex obtuse in outline, the base oblique and 
with a deep sinus, the lower portion extended into a 3 mm. long 
ascending hastate lobe which lies over the stem; nerves delicate, 
the lower side 3 the upper side only 2-nerved; stipule ciliate, 2 to
